What is x when 20 divided by x equals 66?

To find the answer, just divide the dividend by the quotient: 20 ÷ 66 = 0.3030303030303

To prove this, let's compute 20 divided by 0.3030303030303: $\frac{20}{0.3030303030303} = 66$

How does it work?

Asking what the value of x could be when 20 divided by x gives a result of 66, is equivalent to solving the following equation:

$\frac{20}{x} = 66$

Multiply both sides by x: $\frac{20 x}{x} = 66 x$
$\frac{20 x}{x}$ is equivalent to $\frac{x}{x} \times 20$ , which simplifies to $1 \times 20$ (or just $20$ ).
Thus, the equation becomes: $20 = 66 x$
To find x, divide both sides by 66: $\frac{20}{66} = \frac{66 x}{66}$
Which gives, after simplification: $0.3030303030303 = x$ (or $x = 0.3030303030303$ )

So, if the dividend is 20 and the quotient is 66, the divisor is 0.3030303030303.
